Hello @adrew ,
Thank you for reaching out to the Instructure Community. I understand you are receiving an error : Request is forbidden/unauthorized . What action are you performing in Canvas when you see this error ? Are you seeing the error in Canvas or in Power school ? This error may occur when attempting to pass back grades to Power School.
If you are seeing the error when attempting to pass back grades in a course, I might recommend reaching out to Support. It is possible that we can address this issue for you. Canvas Support may be able to directly pinpoint the source of the issue and provide a resolution: How do I contact Canvas Support? - Instructure Community .
